EL DINERO que provocó el colocón de ayer no venía sólo de los bancos centrales europeos sino también, al parecer, de la Reserva Federal de los Estados Unidos:

The Federal Reserve late Sunday opened a program to ship U.S. dollars to Europe in a move to head off a broader financial crisis on the continent.

Other central banks, including the Bank of Canada, the Bank of England, the European Central Bank, the Swiss National Bank and the Bank of Japan also are involved in the dollar swap effort.

The move comes after the European Union and International Monetary Fund pledged a nearly $1 trillion defense package for the embattled euro, hoping to calm jittery markets and halt attacks on the eurozone's weakest members. The ECB also jumped into the bond market Sunday night, saying it is ready to buy eurozone bonds to shore up liquidity in "dysfunctional" markets.

The Fed's action reopens a program put in place during the 2008 global financial crisis under which dollars are shipped overseas through the foreign central banks. In turn, these central banks can lend the dollars out to banks in their home countries that are in need of dollar funding to prevent the European crisis from spreading further.
